Product Description

Product Description

The fixed flanged ball valve is a high-performance cutting-type valve specially designed for harsh industrial conditions. Its core structure features an upper and lower shaft-fixed ball design, which is different from the floating ball valve. Under the pressure of the medium, the ball does not undergo any axial displacement. The valve seat with a pre-tightening spring is used to achieve bidirectional sealing compensation. Connection type: Standard flange connection (compliant with ASME B16.5, GB/T 9113, etc.), supports various custom flange surfaces such as RF, RJ, FM, etc., and is suitable for industrial pipeline installation requirements.
Pressure and diameter range: Covers Class 150~2500 (PN16~PN420) pressure grades, with diameters ranging from NPS 1/2" to NPS 48", and supports both full-bore / reduced-bore flow channel designs.
Material configuration: The valve body can be made of carbon steel (WCB), stainless steel (CF8/CF8M, CF3/CF3M), duplex steel, alloy steel, etc.; the valve seat can be selected as a soft seal (PTFE, RPTFE, PEEK) or a hard seal (Stellite alloy welding), suitable for different working conditions such as water, oil, natural gas, corrosive media, and media containing solid particles.
Standard and safety design: Strictly follows industry standards such as ASME B16.34, GB/T 12237, etc., standardizes with fireproof and anti-static structures, valve stem anti-slip design, and optional double shut-off and discharge (DB&B) functions, as well as mid-chamber cleaning / grease injection devices.
Drive mode: Supports manual worm gear / handwheel drive, pneumatic, electric, hydraulic, etc. forms, and can be equipped with locking devices, limit switches, etc.
Application scenarios: Widely used in industries such as petroleum, natural gas, chemical, power, metallurgy, long-distance pipelines, etc., for medium cutting, transportation, and diversion control.

High-pressure and large-diameter conditions have strong adaptability
The ball is fixed by the upper and lower valve rods, and the medium pressure is borne by the valve seat. The ball does not move, and the sealing performance is not affected by the diameter and pressure. It is especially suitable for Class 600 and above high-pressure, NPS 4" and above large-diameter conditions, solving the pain points of large-diameter floating ball valves with high operating torque and unstable sealing.

High degree of customization, suitable for complex requirementsIt can be customized for materials, sealing forms, driving methods, flange standards, etc. according to the user's working conditions. It supports customized designs for special working conditions such as low temperature, high temperature, strong corrosion, and sulfur-containing media, meeting the differentiated needs of different industries.

Packaging & ShippingYour Goods, Safely Shipped from Our Factory Floor to Your DoorstepAt RST Valve, we don't just manufacture valves — we ensure they arrive in perfect condition, no matter the distance.---Every valve is individually wrapped in plastic bag with protective caps on connection end to preventing rust, scratches, and damage during transit.---All valves are well packed into plywood cases.

FAQQ1: Are you a manufacturer or a trading company?A: We are a professional valve manufacturer located in Wenzhou, China, with over 15 years of experience. We welcome factory visits.Q2: What certifications do you hold?A: We are ISO, CE, EAC,TS certified. Our products strictly comply with ANSI, DIN, JIS, BS, and GB standards.Q3: Do you offer OEM/ODM services?A: Can add chat apps such as WhatsApp WeChat or Facetime, etc.A: Yes. We can customize valve body logos, materials (e.g., CF8M, WCB), connection types, and pressure ratings according to your drawings or samples.Q4: For Ball Valves, do you offer both floating and trunnion-mounted designs?A: Yes. We supply Floating Ball Valves (for smaller sizes, e.g., DN15-DN200) and Trunnion-Mounted Ball Valves (for larger sizes, e.g., DN200 and above) to reduce operating torque and ensure stability.Q5: What is the difference between Rising Stem and Non-Rising Stem Gate Valves?A: We manufacture both types. Rising Stem Gate Valves allow operators to visually see if the valve is open or closed (common in above-ground installations), while Non-Rising Stem Gate Valves are suitable for underground or limited vertical space applications.Q6: Do your Globe Valves offer good shut-off capability?
A: Absolutely. Globe Valves are specifically designed for throttling and regulating flow. They provide superior tight shut-off compared to gate valves but have a higher pressure drop. We ensure the disc and seat are precisely machined for a perfect seal.

Q7: Which type of Check Valves do you recommend for low-pressure systems?
A: For low-pressure or non-return applications where water hammer is a concern, we recommend our Swing Check Valves or Wafer Check Valves. They offer low cracking pressure and minimal flow resistance.

Q8: What mesh size do you use for Y Strainers?
A: Our standard Y Strainers come with a 40-mesh or 80-mesh stainless steel screen. Custom mesh sizes (e.g., 60-mesh, 100-mesh) are available upon request for filtering finer particles.

Q9: How do you protect valves during shipping?
A: We apply anti-rust oil, use plastic film wrapping, and install end protectors on all connection ends. Larger valves are packed in reinforced plywood cases to prevent damage during sea freight.

Q10: Can I get a sample for testing?
A: Yes, sample orders are accepted. The sample cost is refundable once you place a bulk. order.
